The shield is clearly protecting against meteoroids. I don't think this
is ambiguous at all. Similarly, one might want to protect Earth from
asteroid impacts, but you would not say it needed protection from
meteorites. It isn't the leftover bits that present the hazard... it is
the incoming projectiles you have to guard against.
